To all whom it may concern:

Be it known that I, PAUL HEILMANMDU- COMMUN, engine-manufacturer, of Mulhouse, Alsace, have invented certain new and useful Improvements in Machinery for Combing Fibrons Substances, (for which I have obtained patents in Germany,rNo.,6,244. September 11, 1878, No. 7,445, March 27, 41879, No. 7,772, February 11, 1879, and No. 8,167, April 22, ro 1879; iu England, No. 4,508, November 29, 1877, No. 3,836, September 28, 1878, and No. 547, February 11, 1879; in France, No. 120,910, November 8, 1877, No. 122,573, February 21, 1878, No. 126,092, August 24, 1878,No. 123,709, I5 April 8, Y 1878, and No. 128,506, January 1, 1879; Italy, Vol. 22, No. 16, May 31, 1879, second series, Vol. 10, No. 316, June 30, 1879; Austria, Glass XIV, 376, Vol. 29, page 1358, October 17, 1879; Belgium, No. 48,040, April 2o 26, 1879, and Spain, No. 253, folio 74, June 30, 1879,) of which the following is a specification.

My invention relates to that class of fibercombing machines described in Patent No.

Charles V. Steinlen on the th of February,

1880, to which patent I refer for adetailed description of the general features and operation of the machine.

My improvements are as stated specifically in the following description.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in Which- Figure 1 is a side elevation of the rotary comb and its accessories. Fig. 2 is a sectional View of the gearing for transmittingmotion from thelotary comb to its cleaning-brushes. 4o Fig. 3 is a horizontal section on the line 23 23, Fig. 1.- Fig. 4 is a sectional elevation of the holding-nipper, gill-box feed, and mechanism for operating the same. Fig. 4a is an elevation of the nippers, showing the manner ofsccuring the'upper'jaw thereof to the frame of the machine and thevmechanisln for imparting to it the necessary reciprocating motion. Fig.

5 is a vertical transverse section of the entire machine, showing the rotary comb and the gill-box feed. Fig. Gis a diagram illustrating 5o` a stationary nipper constructed with a holding lip ortinger, as heretofore used. Figs. 7 to 14, inclusive, are vertical sections of the stationary nipper, illustrating the action of my improved movable holding-finger in present. 55 ing the head of the web to the action of the rotary comb. Figs. 15 and 16 are vertical sec. tions ofthe holding-nipper and lip and of the stop employed to lift the lip upon the approach of the rotary comb. Figs. 15a and 15" are de- 5o tail views of parts of the device shown in Figs.

15 and 16 removed. Fig. 17 is a vertical section showing a stop of modified form for accomplishing the same object. Figs. 18 and 19 are diagrams illustrating, respectively, roller and porcupine feeders heretoforevused, showing the necessary distance of their holdingpoints in rear of the face of the nipper. Figs.

' 20 and 21 are respectively avertical transverse section and side elevation of a gill-box pro- 7o vided with bars, one of which is constructed to serve as a supplementary nipper in rear of the holding-nipper B B. Figs. 22 and 23 are transverse sections showing in `two positionsv the parting-nipper provided with a supplemental lip moving relatively to its upperjaw,

so as to prevent the adhesion of the web thereto. Figs.'24 and 25 are respectively a transverse section and afront elevation of another'form of mechanism for imparting the 8O required relative movements to the movable finger of the holding-nipper and the rotary comb.

It has been found in practice that the slotted rock-shaft for actuating the drawing-nipper and regulating its stroke did not afford sufficient adjustment, and in order to obviate this difficulty I have provided a means whereby the drawing-nipper may be made to perform its oscillations within any desired distance of 9o two portions and connect the adjoining ends by a nut, h1", provided with right and left threads, so that by turning the nut the bar may be lengthened or shortened,according as short or long fibers are being combed. Instead of the crank as heretofore used in this class of machines for operating the drawing-nippers,I now prefer to employ one or more eams,as the regular motion ot' the crank is ill adapted to the proper distribution of time in makingthe oscillation forward and backward, it. being desirable that the nipper should remain stationary for a certain period at each end ofthe stroke, and that it should proceed with an,

accelerating movement from the beginning nearly to the end of the drawing-stroke and rapidly on its return-stroke. In order to accomplish this motion the connecting-rod H' is provided with a yoke, 71,', which embraces the shaft G', so as to serve as a guide and support for the said rod, and at opposite ends of said yoke I provide anti-friction rollers ZX Z'X, which bear against the cams Z Z', thatimpart through them and the rod II', pivoted lever H" H'", and rod Hl" the desired irregular motion to the drawing-flippers.

Fig. 4 shows the mode of applying the gillbox feed mechanism to this class of combingmachines. rIhe upper frame, A', of the gill` box has attached to its under side the gills c', and receives a vertical motion from the cam Q', operating through hell-crank lever Q, and both the upper part, A', and the lower part, A", receive an adjustablehorizontal movement from cams M M', operating through levers LX L'X IX and oscillating cheek-plates A'".

a'" a'" are bars forming a grating to facilitate the withdrawal of the gills a from the web, the said bars being connected together at their ends, and also to the base A" of the gill-box, the bars and base being pivoted ata to the cheek-plates A". These cheek-plates are pivoted at q and have in their upper edges slots f', concentric with the pivots q" of the levers Q, which slots receive and guide studs f on the upper plate, A'. The studs f extend outside the cheek-plates A'" and rest in horizontal notches in the ends ot' the arms Q, as shown in Fig. 2l.

The lower jaw, B, of the nipper is stationary, while the upper jaw, B', is movable to and from it, said jaws operating in conjunction with each other to produce the saaie result as the jaws of the nipper in Patent No. 224,428, above referred to. The nipper-jaw has a slotted or other connection, PXX, with the frame of the machine, which will permit it to be moved by the cam I? through the bell-crank lever P'. One arm, P", of this bellcrank lever is loosely connected to the jaw B', as represented in Fig. f1, and when rocked on its fulcrum 1?'I causes said jaw to move to or from thejaw B.

Then using a pair of rollers or a porcupinecylinder for feeding, as shown in Figs. 18 and 19, the web is held at a point too far in rear of the partingline, and in neither ease is the nipping-surface sufficiently broad to accomplish the desired result. To remedy these defects in an improved manner one or more of the bars ct'", which occupy the spaces between the gills a', are replaced by a bar, am, that extends down below the bars a", as shown in Fig. 20, in order to nip the bers in rear of the nippers B B' while said nippers are closing. In the drawings this nipping-bar @"'X occupies the second space; but any one of the other bars ct'" may be replaced, according to the length of the fiber being drawn. These nipping-bars a'"" are depressed by the top A' of the gillbox, and have flat end studs or extremities al', which project through slots c" in the cheekplates A'" and rest on the free ends of steel springs r, which are secured to the cheek-plates A'" at r and serve to lift the bar @"'X after it has been depressed by the top A' of the gillbox.

It is sometimes desirable to substitute a rotary comb for the lower reciprocating comb described in the aforesaid Patent No. 224,428, and in Figs. 1, 2, and 3 I have shown a means of adapting and operating such a Comb in this class ot machines.

The rotary comb C'" is journaled in a triangular frame, D,wl1ich is pivoted at d', and receives an oscillating movement about said pivot to and from thcholding-nippcr by means of cam D'. The comb is driven from the shaft d by bevel-gears 5 6 7 S and shaft e'". The frame D carries, also, a stripping or cleaning brush, W'", for removing the waste from the comb,l said brush being driven by the gearing 10 l1 l2 13 from the gear-wheel 9 on the combshaft. The brush W'" is regulated in position with regard to the comb cylinder G'" by setserew Z" operating the lever l", said lever bcing clamped in position by bolt ZW.

The limit to the upward movement of the rotary comb is regulated by set-screw c" in stop J (against which the frame D strikes at the end of its upward stroke) and by lever D", pivoted at d" to the frame D, adjusted by means ot set-screw dl" and slot d" and bearing against cam D'.

In Fig. 6, F represents the lip or finger which is usuallyemployed to present the front end of the web or sliver to the action of the comb. According to the present invention t-he lip or finger, instead of beinga Xture upon the stationary `jaw, is made movable up and down in the direction of the arrows ax, Figs. 7, 8, and 9, and to and from the nipper in the direction ofthe arrows 11X. 'Ihe former of these motions is accomplished by attaching the lip F to the vertically-sliding face EX, which is attached to the rod GX, against which the frame D impinges as it nears the upper end of its stroke, thereby maintaining a constant distance between the center I?X ofthe comb 0 and the lip F after the comb has risen to within a certain distance of the nipper. The same object may, however, be obtained by the device illustrated in Fig. 17, which shows the employment of a roller, KX,

IOO

pivoted to the lip-holderEX and running on the edge of a disk, LX, mounted von the combcylinder, the disk LX being mounted eccentrically on the shaft PX, so as to give the necessary up-and-down movement to the lip. The movement of the lip to and from the nipper is accomplished either by pivoting the lip to the face EX, as in Figs. 7 and 10 to 17, inclusive, or else by securing the lip to the face, as in Figs or 9, and allowing it to spring away therefrom and return thereto by reason of its own elasticity.

Figs. 24 and 25 illustrate still another mode of operating the lip-holder EX relatively to the rotary comb. C1V is aconnecting-rod pivoted to EX and operated by cam N through lever and friction-rollers HV i'orraising and lowering the lip-holder. The comb-carrying arm D, Fig. 25, strikes against the adjustable stop G as it nears the upperend of its stroke and thereby lifts the roller HV from the cam N, and from thence upward the comb and lip move in unison. When the pivoted form is used, a spring, R, will be necessary to hold it against the nipper-face. rlhis vertical play of the lip F enablesthe line of attack upon the front end of the web to be varied from its point, as in Fig. 10, to its central portion, as in Fig. 11 and then to its base, as in Fig. 12. The combing may either be completed in this position of the comb-cylinder or it may be tinished at the point of the front end, as illustrated in Fig. 13, with iine-tooth brush CX and a rubber, DX, for smoothing the web and neutralizing the electricity generated by the passage of the teeth; or the operation upon the front end of the web may terminate in the posit-ion shown in Fig. 14.

The horizontal play given the lip F enables it to yield and move away from the teeth should any exceptional amount of work come upon it.

In order to prevent the web or sliver adhering to the upper jaw, S, of the drawing-Dipper when itopens, I have .found it necessary to apply a lip, L"X, Figs. 22 and 23,which slides on a guide, h', secured to said jaw S,and by means of the spring HX is caused to hold the sliver to the lower jaw, R', until the upperjaw, S, strik ing against the upper part, h', of the lip L"'X, lifts the same and liberates the ber.

I am aware that the means employed by me for adjusting the lengt-h of the connecting-rod vHI" is not new, and do not claim such as my invention.
